I have written an article that the First Chola King was from the Solar Dynasty of Ikshvaku the ancestor of Rama.
In another article I mentioned that Lord Rama,s ancestor Satyavrata Manu migrated from the South because of a Tsunami to Ayodhya , whose son Ikshvaku founded the Ikshvaku Dynasty, to which Lord Rama belongs.
Some researches show that the facts mentioned are correct and they corroborate the fact that the Cholas indeed were the descendants of the Solar Dynasty of Lord Rama.
“Cholas claimed their descent from Sun and solar race kings ( Surya vamsis). Cholas worshipped Sun and built several Sun Temples. Konark Sun Temple was built in Orissa by Chola prince who was daughter of Rajaraja and wife of Vimaladitya. One Mudiraj ancestor Dharma Choda chari was said to belong to solar race. Chola- Mutharayar research center concluded that Cholas and Mutharayars belonged to one family tree. Some of the chola surnames among the Mutharayars of Tamilnadu are as given below :Cholamutharayar, Cholan, Cholavalavan, Cholavallakamayar, Killirayar,Killivazhavan,Karikalarayar,Valavan,Valavar. The Cholas claimed their descendancy from Manu, Ikshvaku, Mandhata, Mucukunda and Sibi. A prominent warrior race, cholas are central to many ancient tamil literary works, which describe them as benevolent, courageous and just. They were supposed to have descended from sun and thus were scions of the legendary royal solar dynasty, heirs to a tradition begun centuries ago. Many Chola kings took names and titles ‘sibi’ to probably acknowledge their descent from that legendary king who is celebrated as a paragon of justice. Medieval chola kings took titles like ‘Parakesarin’ and ‘Rajakesarin’ remembering their remote ancestors of that same illustrious lineage who were supposed to have lived centuries and even millenniums before them. The chola country is mentioned by Greek chroniclers and merchants, a more detailed description is provided in works of Ptolemy a Roman trader of 1st century A.D. The recent excavations following tsunami of 2004 has helped throw more light into poompuhar,(Kaveryppattanam) the capital city of early cholas. Evidently, poompuhar was an important port city in the ancient world. It was a place from which traders set sail to far east. Among the greatest of early chola kings was karikala, who according to various tamil literary sources during first century A.D defeated all his southern neighbors. He is also credited with building efficient irrigational systems and canals. The fact that he was benevolent is brought out by a poem which was written on his death. Kampan composed his poem (Tamil Kamba Ramayana) during the reign of the largest and most powerful Tamil kingdom, the imperial Cholas. Sholas might have supported this literature keeping in view of their descendancy to solar race to which Srirama belonged. Under the umbrella of that expanding empire, which claimed victories from the Ganga to Sumatra, Rama shrines were built, extensive sets of Ramayana reliefs were carved along the base of several temples, and temples supported recitations of the Rama story. Chola monarchs also bore Rama’s name in their imperial titles, and apparently one raja perceived parallels between his conquest and Rama’s when he erected icons to the epic hero to celebrate a victory over the Sinhala kings of Lanka. One temple inscription goes so far as to suggest the story of Rama as an origin myth for the Cholas, which was a solar dynasty like Rama’s. The Cholas belonged to the Solar and the Chalukyas to the Lunar race. The former were generally Saivas and the latter were Vaishnavas as they had the boar for their crest. Besides, the Chalukyas were also patrons of the Jainas. Cholas connection to solar race kings consolidated through Rangavimana : Manu’s son Ikshwaku cherished the desire of possessing the Ranga Vimanam for the benefit of the people on earth. He consulted his family preceptor, Vasishtha (priest of the Surya vamsha), who advised him to start penance uttering the sacred Ashtakshara Mantra. Accordingly, Ikshwaku started a severe penance which puzzled even the devas, foreboding evil days for them. They attempted to spoil the penance by deputing Maninatha and the celestial nymphs to distract his attention. Indra took the lead in this affair and did not even hesitate to send the Vajraayudha (lightning weapon) to foil the penance. But all failed in their attempts. In disappointment, they prayed to Brahma, to save them from the baffling catastrophe. Brahma on his part approached Ranganatha for advice. Ranganatha consoled Brahma by expressing his desire to go to Ayodhya where he would be worshipped by the descendant of the Solar dynasty for four yugas, and at the end of the fourth yuga he would go to the kingdom of the Cholas in the South, on the banks of the Kaveri, where he would stay for 700 years. At the end, of this period he would return to Brahmaloka. Brahma was directed to part with the Ranga Vimanam to Ikshwaku. Cholas were Kolis : One Gandaraditya in one of the hymns calls himself ‘king of Kori’ and ‘lord of Tanjai’. This means that he belonged to the Chola royal family as per historians. Koris and Kolis are one and the same people. Mudiraj and Muthuraj people are said to be kolis of South India. Koris <=> kolis => Kolas => Colas => CholasGangaikonda Chola : According to the Kalingattu-Parani, Kulottunga’s father belonged to the lunar race, and his mother was the daughter of Gangaikonda-Chola .
‘. One other ancestor of Sri Rama, Musu Kunthan, is none other than the Musu Kuntha Chola in ancient Tamil history. This Musu Kunthan’s reign was during the second Tamil Sangam age 4800-2800 BC.’
